Background: Premature delivery is among the leading causes of perinatal mortality and morbidity in developed societies, which is an important obstetrics problem. Maternal periodontitis is a prevalent condition that has been suspected to be associated with adverse pregnancy outcomes such as premature birth. However, there are still conflicting results about this possible relationship, therefore this study was designed to test the association between maternal periodontitis and premature birth. This study also provides information about a new screening tool recommended for use by nurses and midwives to screen for periodontal diseases during antenatal consultations in order to improve the health of mothers and children., Methods: A retrospective case-control study was conducted at 12 health facilities in the Southern Province of Rwanda from February to August, 2018. A total of 555 women in the postpartum period were enrolled in the study. Cases and controls were enrolled in a ratio of 1:2; each enrolled case of preterm birth was followed by 2 unmatched control subjects that were next on the register and who delivered at term gestation. A total of 185 cases of preterm deliveries and 370 controls of term delivery were enrolled in the study. Multivariate regression analysis was used and the independent variables were hierarchically entered in three groups: The first group involved demographic variables that were put in the regression model as Step 1. The second group was made up of other potential risk factors that were placed in the regression model as the second step. Periodontitis was entered in the final regression step, as it was hypothesized as the main predictor variable., Results: A statistically significant association was found between periodontitis and premature birth. Women who had periodontitis had 6 times the odds of giving birth to premature birth infants compared to women who had no periodontitis (OR: 6.360, 95% CI 3.9, 10.4)., Conclusion: The study results indicate that periodontitis is strongly associated with premature birth. Preventive solutions including the use of a periodontitis screening tool for nurses and midwives during antenatal care consultations, are highly recommended.

Of the five agriculturally important mycotoxins, AFB 1 , FB 1 , DON, ZEA and OTA, a well-characterized biomarker of exposure in blood is only available for aflatoxin. Working with a population of 139 women of childbearing age in Rwanda, we undertook a comprehensive assessment of their dietary mycotoxin exposure. Using high-resolution LC-MS/MS with stable isotope dilution analysis, the albumin-aflatoxin adduct was quantitated in plasma. Similarly, AFM 1 , AFB 1 , AFG 1 , FB 1 and B 2 , OTA, zearalenone, α-zearalenol, deoxynivalenol, deoxynivalenol-15-glucuronide and deoxynivalenol-3-glucuronide were quantitated in urine. AFB 1 -Lys was detected in plasma from 81% of the women, indicative of exposures 1-2 orders of magnitude above current guidance. Zearalenone and/or α-zearalenol were detected in the urine of 61% of the women, the majority of whom had estimated exposures 2-5 times the PMTDI, with one third more than an order of magnitude above. Urinary deoxynivalenol or the two glucuronide conjugates were found in 77% of the participants. Of these, 60% were below the PMTDI, 28% were twice and 12% were >10x the PMTDI. Fumonisin B 1 (30%) and ochratoxin A (71%) were also detected in urine. Exposures observed in these Rwandan women raise serious food safety concerns and highlight the need for authorities to help manage multiple mycotoxins in their diet., (Crown Copyright © 2020.

Background: The WHO Maternal Near Miss (MNM) approach was developed to evaluate and improve quality of obstetric care worldwide. This study aimed to study the incidence of MNM and quality of care at a district hospital in rural Rwanda by applying this approach., Methods: A facility based, prospective cohort study conducted at a district hospital in rural Rwanda between June 2013 and December 2014. Subjects were followed from time of admission to discharge or death., Results: In 3979 deliveries, 3827 singletons and 152 twins pairs were born. Among the 4131 neonates, there were 3994 live births and 137 stillbirths. Ninety-nine women suffered severe maternal outcome (SMO): 86 maternal near misses and 13 deaths. This adds up to a maternal near miss ratio of 21.5 per 1000 live births (95 % CI 17.3-26.5), a maternal mortality ratio of 325 per 100 000 live births (95 % CI 181-543) and a mortality index of 13.1 % (95 % CI 7.3-21.9). Hemorrhage (n = 49, 57 %) and hypertensive disorders (n = 27, 31.4 %) were the commonest MNM conditions. Eclampsia (n = 4/13; 30.7 %) was the leading cause of maternal mortality, while sepsis/peritonitis following cesarean section (n = 2/6; 33.3 %) had the highest mortality index. Seventy-seven out of 99 SMO cases (77.9 %) were referred from other facilities with critical conditions and 28 out of 99 SMO cases (28.3 %) were admitted into the Intensive Care Unit. Several indicators such as administration of oxytocin, magnesium sulfate and antibiotics were found to be suboptimal., Conclusions: MNM is common at district level in Rwanda. The MNM approach enabled us to identify shortfalls in clinical practice and the referral system.

Background: To determine the prevalence and factors associated with severe ('near miss') maternal morbidity and mortality in the University Teaching Hospital of Kigali-Rwanda., Methods: We performed a cross sectional study of all women admitted to the tertiary care University Hospital in Kigali with severe "near miss" maternal morbidity and mortality during a one year period using the WHO criteria for 'near miss' maternal mortality. We assessed maternal demographic characteristics and disease processes associated with severe obstetric morbidity and mortality., Results: The prevalence of severe maternal outcomes was 11 per 1000 live births. The maternal near miss ratio was 8 per 1000 live births. The majority of severe obstetric morbidity and mortalities resulted from: sepsis/peritonitis (30.2%)--primarily following caesarean deliveries, hypertensive disease (28.6%), and hemorrhage (19.3%). Majority of our patients were found to be of lower socioeconomic status, refered from district hospitals to the tertiary care center, and resided in the eastern part of the country., Conclusion: The main causes associated with MNH were peritonitis, hypertensive disorders and bleeding. The high prevalence of peritonitis may reflect suboptimal intraoperative and intrapartum management of high-risk patients at district hospitals. Direct causes of severe maternal outcome are still the most prevalent. The study identified opportunities for improvement in clinical care to reduce potentially these adverse outcomes.

Background: Preterm birth (PTB) is a leading cause of early childhood mortality and morbidity, including long-term physical and mental impairment. The risk factors for PTB are complex and include maternal nutritional status and infections. This study aimed to identify potentially modifiable risk factors for targeted interventions to reduce the occurrence of PTB in Rwanda.Methods: We conducted a prospective, longitudinal cohort study of healthy pregnant women aged 18 to 49 years. Women at 9-15 gestational weeks were recruited from 10 health centers in Gasabo District, Kigali Province between September and October 2017. Pregnancy age was estimated using ultrasonography and date of last menstruation. Anthropometric and laboratory measurements were performed using standard procedures for both mothers and newborns. Surveys were administered to assess demographic and health histories. Categorical and continuous variables were depicted as proportions and means, respectively. Variables with p <  0.25 in bivariate analyses were included in multivariable logistic regression models to determine independent predictors of PTB. The results were reported as odds ratios (ORs) and 95% confidence intervals (CI), with statistical significance set at p <  0.05.Results: Among 367 participants who delivered at a mean of 38.0 ± 2.2 gestational weeks, the overall PTB rate was 10.1%. After adjusting for potential confounders, we identified the following independent risk factors for PTB: anemia (hemoglobin < 11 g/dl) (OR: 4.27; 95%CI: 1.85-9.85), urinary tract infection (UTI) (OR:9.82; 95%CI: 3.88-24.83), chlamydia infection (OR: 2.79; 95%CI: 1.17-6.63), inadequate minimum dietary diversity for women (MDD-W) score (OR:3.94; CI: 1.57-9.91) and low mid-upper arm circumference (MUAC) < 23 cm (OR: 3.12, 95%CI; 1.31-7.43). indicators of nutritional inadequacy (low MDD-W and MUAC) predicted risk for low birth weight (LBW) but only UTI was associated with LBW in contrast with PTB.Conclusion: Targeted interventions are needed to improve the nutritional status of pregnant women, such as maternal education on dietary diversity and prevention of anemia pre-pregnancy. Additionally, prevention and treatment of maternal infections, especially sexually transmitted infections and UTIs should be reinforced during standard antenatal care screening which currently only includes HIV and syphilis testing.

Objective: Assess the primary causes and preventability of maternal near misses (MNM) and mortalities (MM) at the largest tertiary referral hospital in Rwanda, Kigali University Teaching Hospital (CHUK). Methods: We reviewed records for all women admitted to CHUK with pregnancy-related complications between January 1st, 2015 and December 31st, 2015. All maternal deaths and near misses, based on WHO near miss criteria were reviewed (). A committee of physicians actively involved in the care of pregnant women in the obstetric-gynecology department reviewed all maternal near misses/ pregnancy-related deaths to determine the preventability of these outcomes. Preventability was assessed using the Three Delays Model.[] Descriptive statistics were used to show qualitative and quantitative outcomes of the maternal near miss and mortality. Results: We identified 121 maternal near miss (MNM) and maternal deaths. The most common causes of maternal near miss and maternal death were sepsis/severe systemic infection (33.9%), postpartum hemorrhage (28.1%), and complications from eclampsia (18.2%)/severe preeclampsia (5.8%)/. In our obstetric population, MNM and deaths occurred in 87.6% and 12.4% respectively. Facility level delays (diagnostic and therapeutic) through human error or mismanagement (provider issues) were the most common preventable factors accounting for 65.3% of preventable maternal near miss and 10.7% maternal deaths, respectively. Lack of supplies, blood, medicines, ICU space, and equipment (system issues) were responsible for 5.8% of preventable maternal near misses and 2.5% of preventable maternal deaths. Delays in seeking care contributed to 22.3% of cases and delays in arrival from home to care facilities resulted in 9.1% of near misses and mortalities. Cesarean delivery was the most common procedure associated with sepsis/death in our population. Previous cesarean delivery (24%) and obstructed/prolonged labor (13.2%) contributed to maternal near miss and mortalities. Conclusion: The most common preventable causes of MNM and deaths were medical errors, shortage of medical supplies, and lack of patient education/understanding of obstetric emergencies. Reduction in medical errors, improved supply/equipment availability and patient education in early recognition of pregnancy-related danger signs will reduce the majority of delays associated with MNM and mortality in our population.

Background: Animal embryotoxicity data, and the scarcity of safety data in human pregnancies, have prevented artemisinin derivatives from being recommended for malaria treatment in the first trimester except in lifesaving circumstances. We conducted a meta-analysis of prospective observational studies comparing the risk of miscarriage, stillbirth, and major congenital anomaly (primary outcomes) among first-trimester pregnancies treated with artemisinin derivatives versus quinine or no antimalarial treatment.Methods and Findings: Electronic databases including Medline, Embase, and Malaria in Pregnancy Library were searched, and investigators contacted. Five studies involving 30,618 pregnancies were included; four from sub-Saharan Africa (n = 6,666 pregnancies, six sites) and one from Thailand (n = 23,952). Antimalarial exposures were ascertained by self-report or active detection and confirmed by prescriptions, clinic cards, and outpatient registers. Cox proportional hazards models, accounting for time under observation and gestational age at enrollment, were used to calculate hazard ratios. Individual participant data (IPD) meta-analysis was used to combine the African studies, and the results were then combined with those from Thailand using aggregated data meta-analysis with a random effects model. There was no difference in the risk of miscarriage associated with the use of artemisinins anytime during the first trimester (n = 37/671) compared with quinine (n = 96/945; adjusted hazard ratio [aHR] = 0.73 [95% CI 0.44, 1.21], I2 = 0%, p = 0.228), in the risk of stillbirth (artemisinins, n = 10/654; quinine, n = 11/615; aHR = 0.29 [95% CI 0.08-1.02], p = 0.053), or in the risk of miscarriage and stillbirth combined (pregnancy loss) (aHR = 0.58 [95% CI 0.36-1.02], p = 0.099). The corresponding risks of miscarriage, stillbirth, and pregnancy loss in a sensitivity analysis restricted to artemisinin exposures during the embryo sensitive period (6-12 wk gestation) were as follows: aHR = 1.04 (95% CI 0.54-2.01), I2 = 0%, p = 0.910; aHR = 0.73 (95% CI 0.26-2.06), p = 0.551; and aHR = 0.98 (95% CI 0.52-2.04), p = 0.603. The prevalence of major congenital anomalies was similar for first-trimester artemisinin (1.5% [95% CI 0.6%-3.5%]) and quinine exposures (1.2% [95% CI 0.6%-2.4%]). Key limitations of the study include the inability to control for confounding by indication in the African studies, the paucity of data on potential confounders, the limited statistical power to detect differences in congenital anomalies, and the lack of assessment of cardiovascular defects in newborns.Conclusions: Compared to quinine, artemisinin treatment in the first trimester was not associated with an increased risk of miscarriage or stillbirth. While the data are limited, they indicate no difference in the prevalence of major congenital anomalies between treatment groups. The benefits of 3-d artemisinin combination therapy regimens to treat malaria in early pregnancy are likely to outweigh the adverse outcomes of partially treated malaria, which can occur with oral quinine because of the known poor adherence to 7-d regimens.Review Registration: PROSPERO CRD42015032371.

Background: Rwanda has made remarkable progress in decreasing the number of maternal deaths, yet women still face morbidities and mortalities during pregnancy. We explored care-seeking and experiences of maternity care among women who suffered a near-miss event during either the early or late stage of pregnancy, and identified potential health system limitations or barriers to maternal survival in this setting.Methods: A framework of Naturalistic Inquiry guided the study design and analysis, and the 'three delays' model facilitated data sorting. Participants included 47 women, who were interviewed at three hospitals in Kigali, and 14 of these were revisited in their homes, from March 2013 to April 2014.Results: The women confronted various care-seeking barriers depending on whether the pregnancy was wanted, the gestational age, insurance coverage, and marital status. Poor communication between the women and healthcare providers seemed to result in inadequate or inappropriate treatment, leading some to seek either traditional medicine or care repeatedly at biomedical facilities.Conclusion: Improved service provision routines, information, and amendments to the insurance system are suggested to enhance prompt care-seeking. Additionally, we strongly recommend a health system that considers the needs of all pregnant women, especially those facing unintended pregnancies or complications in the early stages of pregnancy.

Background: The objective of this study is to evaluate 'near miss' and mortality in women with postpartum infections.Methods: We performed a retrospective review of all patients referred to the University Teaching Hospital of Kigali (CHUK) between January 2012 and December 2013. We identified 117 patients with postpartum infections. Demographic data, length of admission, location of referral, initial surgery and subsequent treatment modalities including antibiotic administration and secondary surgery were recorded. The primary outcome of interest was a composite of maternal mortality and "near miss" defined as more than one laparotomy with/without hysterectomy and prolonged hospitalization.Results: Diagnoses at CHUK were: pelvic peritonitis (56 %), deep surgical site infection including fasciitis (17 %), and endometritis (15 %). The primary procedures performed prior to transfer were: cesarean section (81 %), septic abortion management (12 %), and vaginal delivery (7 %). Antibiotics were initiated prior to transfer in 66 % of women. Surgery was required in 73 % of patients. Hysterectomies were performed in 22 % of patients. Maternal death occurred in 5 % of the patient population. The primary outcome of severe maternal morbidity and mortality occurred in 90 patients (77 %).Conclusion: Peritonitis-primarily as a result of cesarean deliveries-is associated with significant morbidity and mortality in our population.

Abstract: Objective: To measure maternal and fetal hemodynamics during acute malaria in pregnancy. Methods: Time courses of maternal heart rate (MHR), maternal blood pressure (BP), and fetal heart rate (FHR) were performed until 56days after initiation of anti-malarial treatment with artemether–lumefantrine. Women with malaria were hospitalized for at least 3days until recovery. Results: Mean baseline characteristics of pregnant women with malaria (n=38) versus pregnant women without malaria (n=39) were as follows: gestational age (28.8 vs 24.6weeks; P =0.006); maximum FHR (165.3 vs 158.3 beats per minute [bpm]; P =0.054); minimum FHR (137.6 vs 128.7bpm; P =0.016); mean BP (74.7 vs 80.9mm Hg; P =0.001); pulse pressure (40.3 vs 42.1mm Hg; P =0.300); and MHR (107.4 vs 81.3bpm; P <0.001). The geometric mean parasite count was 13 795 per μL. Complete time courses were collected from a subgroup of participants. For women with malaria, maternal body temperature and BP normalized within 24hours and after 72hours, respectively. The MHR among pregnant women without malaria showed a physiologic increase during pregnancy of approximately 7bpm between days 0 and 56. The mean FHR among women with malaria normalized after 72hours. Conclusion: Acute malaria induces maternal and fetal hemodynamic changes. [Copyright &y& Elsevier]
